The hip-hop star and actor – real name Scott Mescudi – shared an emotional letter to his fans on Facebook, explaining what he's going through.

"It's been difficult for me to find the words to what I'm about to share with you, because I feel ashamed," he began. "Ashamed to be a leader and hero to so many while admitting I've been living a lie.

"Yesterday, I checked myself into rehab for depression and suicidal urges. I am not at peace. I haven't been since you've known me. If I didn't come here, I would've done something to myself. I simply am a damaged human swimming in a pool of emotions every day of my life.

"There's a raging violent storm inside of my heart at all times. Idk what peace feels like. Idk how to relax.

"My anxiety and depression have ruled my life for as long as I can remember, and I never leave the house because of it. I can't make new friends because of it. I don't trust anyone because of it, and I'm tired of being held back in my life."

Kid Cudi continued that he's checking into rehab to "get through this", and hopes to be out in time for ComplexCon, which begins on November 5 in Long Beach, California.

"Love and light to everyone who has love for me, and I am sorry if I let anyone down," he concluded.
